How to paint a wall

Painting a wall is a straightforward project, even for beginner DIYers. However, specific steps need to be taken, in the right order, to ensure a clean look.
Prepare the area: Remove anything attached to the wall, clear the floor of furniture or other objects, and cover the floor with a protective sheet.
Prepare the wall: Wipe it to remove dust, dirt and grease. Repair any cracks or imperfections. Apply a primer if the wall has a glossy or uneven surface, or if you’re painting over a dark colour with a lighter shade.
Painting: Use a paintbrush to cut in along the edges of the wall, including corners, the ceiling and skirting boards. Paint the walls with a roller or paint brush. Allow the first coat to dry completely before applying a second or third coat.
Now read on for the signs that it’s time to repaint.
Fading colour

Over time, the colour of your interior walls starts to fade. Sunlight exposure, particularly in rooms with ample windows, can gradually diminish the vibrancy of the paint.
If you observe a noticeable disparity between the original colour and the present condition of your walls, it’s a clear indication it’s time to apply a fresh coat of paint.
Bubbled paint

Bubbles occur when moisture is trapped beneath the paint surface, causing it to lift and form air pockets. Bubbled paint looks unappealing. Repainting the walls will not only restore their appearance but also address any potential moisture problems.
